If you look at the first picture, you can see that Toyota has avoided the usual cutaway techniques and instead takes a slice from the middle of the block. This chunk o' engine is motorized, and runs up and down while the engine is on display. It makes it difficult to see what's going on in the bottom end, but does an excellent job of showing off the top end.

Check out the vertical intake runners; this looks more like velocity stacks on a race engine than something we'd find in a luxury automobile.
